Drone footage shows scale of US tornado wreckage

Tornadoes that tore through several US states including Arkansas and Illinois have resulted in several deaths and widespread damage to buildings.

Jessica Bahena Hernandez was at a heavy metal gig in Illinois when the roof caved in. She said she narrowly avoided it collapsing on her.

"It was scary because like my first thought when I saw it was more that literally could have been me five minutes prior," she said.
